Kei Nishikori (錦織 圭, Nishikori Kei; [ɲiɕi̥koꜜɾi keꜜː]; born 29 December 1989) is a Japanese professional tennis player. He is the only Japanese man in the Open Era to have been ranked in the top five in singles, reaching his career-high ranking of world No. 4 in March 2015, and the second man in history to do so after Jiro Sato. Nishikori has won twelve titles on the ATP Tour and was runner-up at the 2014 US Open, making him the only man representing an Asian country to contest a major singles final. He also became the first man from Asia to qualify for the ATP Finals, reaching the semifinals in 2014 and 2016. He is currently the No. 1 Japanese player.

In addition, Nishikori defeated Rafael Nadal to win the bronze medal in singles at the 2016 Summer Olympics, bringing Japan its first Olympic tennis medal in 96 years. He holds one of the highest percentages of deciding-set wins in the Open Era and has the second-highest win percentage in matches extending to five sets, with a record of 29–8 and a win percentage of 78.4%.
